Space based OTV servicing

Space based servicing of an orbit transfer vehicle (OTV) was previously outlined in sufficient detail to arrive at OTV and support system servicing requirements. Needed space station facilities and their functional requirements were identified. The impact of logistics and space serviceable design on the OTV design is detailed herein. RL10 derivative rocket engine inspection task times are enumerated

Experimental infectious pancreatic necrosis infections: propagative or point-source epidemic?

AbstractExperimentally initiated epidemics of infectious pancreatic necrosis in rainbow-trout fry were analyzed using a modification of the standard mathematical model for a simple propagative epidemic. Contrary to expectations, the value of the transmission parameter (β) was inversely related to initial density of susceptible hosts. This anomaly can be explained if we assume that the experimental epidemics were point-source rather than propagative epidemics. The implications of this conclusion for modeling experimental and natural epidemics are discussed

Insecticide resistance and vector control.

Insecticide resistance has been a problem in all insect groups that serve as vectors of emerging diseases. Although mechanisms by which insecticides become less effective are similar across all vector taxa, each resistance problem is potentially unique and may involve a complex pattern of resistance foci. The main defense against resistance is close surveillance of the susceptibility of vector populations. We describe the mechanisms of insecticide resistance, as well as specific instances of resistance emergence worldwide, and discuss prospects for resistance management and priorities for detection and surveillance

Social Entrepreneurship and Impact Investing Report

This report investigates the viability of a range of portfolio interventions designed to leverage new sources of investment finance and to support the growth and investability of new businesses in the Indo-Pacific region, with a particular focus on the development of social enterprises. While some of these interventions are relatively new within the aid sector, others are designed to take a fresh perspective on an existing activity. The report sets out the findings for each of the interventions and while interventions were wide ranging, they all form key components of an entrepreneur’s journey and their ultimate participation in an impact investing marketplace. The study focused on the development of new businesses in the region and considers how early stage enterprises could be funded; how entrepreneurs (and particularly social entrepreneurs) could be incubated and supported to develop their business skills; how new financing structures could be deployed by government to attract more private investment into the sector; and the role of platforms in connecting enterprises and sources of capital in brokering deals

Parasites of the Spotted Sucker, Minytrema melanops (Cypriniformes: Catostomidae) from Arkansas and Oklahoma

During October 2015, March and April 2016 and again between March and April 2017, 15 Spotted Sucker (Minytrema melanops) were collected from sites in the Ouachita (n = 5), Red (n = 1), and St. Francis (n = 5) river drainages, Arkansas, and the Arkansas River drainage, Oklahoma (n = 4), and examined for protozoan and metazoan parasites. Found were Calyptospora sp., Myxobolus sp., Pseudomurraytrema alabarrum, Biacetabulum banghami, Penarchigetes oklensis, and Acanthocephalus sp. New host and distributional records are documented for these parasites
